Field Detail

ROOT

public static final LeafRefPath ROOT

Shared instance of the conceptual root schema node.

SAME

public static final LeafRefPath SAME

Shared instance of the "same" relative schema node.

LeafRefPath

protected LeafRefPath(LeafRefPath parent,
                      QNameWithPredicate qname)

Method Detail

create

public static LeafRefPath create(Iterable<QNameWithPredicate> path,
                                 boolean absolute)

Constructs new instance of this class with the concrete path.

Parameters:

path - list of QNameWithPredicate instances which specifies exact path to the module node

absolute - boolean value which specifies if the path is absolute or relative

Returns:

A LeafRefPath instance.

create

public static LeafRefPath create(boolean absolute,
                                 QNameWithPredicate... path)

Constructs new instance of this class with the concrete path.

Parameters:

absolute - boolean value which specifies if the path is absolute or relative

path - one or more QNameWithPredicate instances which specifies exact path to the module node

Returns:

A LeafRefPath instance.

createInstance

protected abstract LeafRefPath createInstance(LeafRefPath newParent,
                                              QNameWithPredicate newQname)

Create a new instance.

Parameters:

newParent - Parent LeafRefPath

newQname - next path element

Returns:

A new LeafRefPath instance

createChild

public LeafRefPath createChild(Iterable<QNameWithPredicate> relative)

Create a child path based on concatenation of this path and a relative path.

Parameters:

relative - Relative path

Returns:

A new child path

createChild

public LeafRefPath createChild(LeafRefPath relative)

Create a child path based on concatenation of this path and a relative path.

Parameters:

relative - Relative LeafRefPath

Returns:

A new child path

createChild

public LeafRefPath createChild(QNameWithPredicate... elements)

Create a child path based on concatenation of this path and additional path elements.

Parameters:

elements - Relative LeafRefPath elements

Returns:

A new child path

getPathFromRoot

public Iterable<QNameWithPredicate> getPathFromRoot()

Returns the list of nodes which need to be traversed to get from the starting point (root for absolute LeafRefPaths) to the node represented by this object.

Returns:

list of qname instances which represents path from the root to the schema node.

getPathTowardsRoot

public Iterable<QNameWithPredicate> getPathTowardsRoot()

Returns the list of nodes which need to be traversed to get from this node to the starting point (root for absolute LeafRefPaths).

Returns:

list of qname instances which represents path from the schema node towards the root.

getParent

public LeafRefPath getParent()

Returns the immediate parent LeafRefPath.

Returns:

Parent path, null if this LeafRefPath is already toplevel.

getLastComponent

public final QNameWithPredicate getLastComponent()

Get the last component of this path.

Returns:

The last component of this path.

isAbsolute

public abstract boolean isAbsolute()

Describes whether schema path is|isn't absolute.

Returns:

boolean value which is true if schema path is absolute.

public final int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

toString

public String toString()
